VALVE Filed Oct. 17, 1931 INVENTOR JACOB .PODOLSK Y flM M ATTORNEYPatented Apr. 25, 1933 JACOB PODOLSKY, F DORGHESTER, MASSACHUSETTS VALVEApplication filed October 17, 1931. Serial no. 569,406.

The present invention relates to valve constructions, and moreparticularly to supports for float valves.

Supports of the above-described character commonly comprise a valve-stemthat supports a bracket comprising a split-ring mounted about anoverflow pipe made of rolled metal, such as brass, the split ends of thering being secured together by a screw. There are three chiectobjections, among others, to this construction. In the first place, thescrew loosens, rendering the device wobbly 31 secondly, the screw has aconstricting tendency against the overflow tube; and thirdly, the rolledmetal corrodes rapidly, in use, to overcome these difficulties, and inrealization of the fact that cast metal does not corrode so readily, theoverflow pipe and the bracket have been cast in one piece,

but this one-piece structure has certain disadvantages.v Other solutionsof the problem have also been proposed, among them the substitution ofthe more expensive copper for brass.

It is an object of the present invention to improve upon valveconstruction of the above-described character. ther objects will beexplained hereinafter. With the above ends in view, a feature 3 of theinvention resides in casting, the overflow pipe integral with a collarfor support ing a separate valve stem-suppo'rting bracket. The collarmay have a supporting portion and an enclosing wall for supportingandconfining a ring integral with the bracket, the ring being heldsecurely in place by a set screw threaded through the enclosing wallinto engagement with the ring.

The'invention will now be explained in connection with the accompanyingdrawing, in which Fig. 1 is an elevation, partly in section, of a valveconstruction of the abovedescribed character, illustrating a preferredembodiment of the present invention, the section being taken upon theline 1-1 of Other and fur- Fig. 2, looking in the direction of thearrows; Fig. 2 is a section taken upon the line 2'2 of Fig. 1, lookingin thedirection of the arrows, the section of Fig. 2 being upon a largerscale; Fig. 3 is an elevation illustrating the invention; Fig. ,4 is aperspective showing the parts detached; and Fig. 5 is a section takenupon the line 55 of Fig. 1, looking in the direction of the arrows.

The overflow pipe 2 is made of cast metal, such as bronze, integral witha collar-4,--and is provided with a valve seat 6 which may be joinedthereto at7. The collar 4 is provided with a supporting portion 8 and anenclosing wall 10, the wall being cut away 60. at 12 on the side next 1to the valve seat. The collar 4 is provided with a second enclosing wall14 parallel to, and concentric with, the enclosing wall 10, so that acir cular groove 16 is formed between the enclosing walls 10 and 14. Asthe walls 10 and 14 are integral with the collar 4, ,a cast bronzestructure is thus provided all in one piece having the groove 16 forreceiving a continuous ring 18 thatvis cast in one piece 7 with an arm20 and valve-stem guide 22. The parts 1 8, 20 and 22 thus constitute abracket separate from the collar 4.

The 2.111120 is provided with a lug '24 at its junction with thering 18and has side walls 26, 28 th'at' engageagainst the cutaway sides 12 ofthe enclosing wall 10. The lower portion 30 of the lug 24 engagesagainst a shoulder 32 that is cut away in the supporting portion 8 ofthe collar 4. The

bottom wall 34 of; the ring 18 is thus supported on the supportingportion 8 and is enclosed'between the walls 10" and 14-,the bottom 30 ofthe lug 24 engaging snugly against the shoulder 32, and the walls 26 andV 28 contacting snugly against the sides 12' of the enclosing wall 10.In this way, the parts are rigidly held together withoutv possibility ofaccidental side play.

Thepipe36 is provided at its lower" end with threads 38 that are screwedinto threads 40 on the inner side of the wall 14:. Not only that, butthey are threaded also into corresponding threads 42 on the inner wallof the ring 18. In this manner, the parts 2 and 36 are joined togetheras a unit and, at the same time, they are made rigid with the collar 18.By reason of this construction, therefore, the valve-stem guide 22, inwhich the valve stem 44 is guided, is held rigidly in place.

To take-up possibilities of residualside play, however, such as mightoccur after periods of use, a universal joint is provided at 46 betweenthe valve' stem 44 and the valve 48 seated on the valve seat 6.

The customary set screw (not shown) may be employed extending throughthe wall 10 into engagement with the ring 18, but it is found inpractice that such set screw: is not needed. I

Modifications will occur to persons skilled in the art and all such areconsidered to fall within the spirit and scope of the invention asdefined in the appended claims.
